Military unit created in the Third Army Corps after a decision was taken not to remove citizens with “suspect political beliefs” from the army’s ranks but instead to assign them to units comprised of “undesirables”. Under the command of Captain Panagiotis Skaloumbakas, it was the harshest and most brutal unit at Makronissos. Because such a large number of soldiers serving in the unit signed repentance declarations, it was dubbed the “blue battalion” and “the pool of Siloam”. Subsequent to its stationing at Makronissos, it was renamed the Third Special Privates Battalion (C ETO).
